ProxOS

ProxOS is a simulated operating system where you learn assembly programming and compete with friends to solve increasingly difficult challenges in different ways.

Write and debug code

You write assembly code that runs on a 32KHz processor. The operating system includes an editor with debugging tools, along with display support and keyboard input for interactive programs.

Challenges and features

You can use custom skins and challenges, and compare results on online leaderboards. The game also includes a manual written by your neighbour and overclocking.
